- A conditional assignment can be done via the following syntax:
_msg = if (alive player) then {"you're alive"} else {"you're dead"} - Posted on June 22, 2009 - 16:27

- It's possible to assign to numbers. Numbers values are not changed. Useful instead of assigning to nul or nil when a result is of no use.
0 = [player] execVM "myScript.sqf"

This operator actually does not return a Nil. It really returns pure Nothing. Not Nil Nothing.
This can cause problems. For example:
_var1 = call { _var2 = ""; };The return value of the "call" is the return value of the "=" operator.
If it were a nil then of cause "_var = nil;" would work just fine.
But in reality this causes a "Generic Error in expression" because you can't assign pure Nothing to anything.
